QT_REQUIRE_VERSION(int argc, char **argv, const char *version)▲
This macro can be used to ensure that the application is run with a recent enough version of Qt. This is especially useful if your application depends on a specific bug fix introduced in a bug-fix release (for example, 6.1.2).
The argc and argv parameters are the main() function's argc and argv parameters. The version parameter is a string literal that specifies which version of Qt the application requires (for example, "6.1.2").
Example:
Sélectionnez
#include <QApplication>
#include <QMessageBox>
int main(int argc, char *argv[])
{
QT_REQUIRE_VERSION(argc, argv, "4.0.2")
QApplication app(argc, argv);
...
return app.exec();
}
